POURER FOR POURING AT LEAST TWO DIFFERENT LIQUIDS

Abstract: A pourer (1, 190, 200, 210, 250, 300, 350, 360) for concurrently pouring at least two different liquids from adjacent containers B, C of a bottle A has a main pourer body (2) with pourer body sections (3, 4) which is engageable, for example by snap fitting, with the respective container B, C. Each pourer body section (3, 4) has a liquid passageway (10, 11) which extends from a liquid inlet (10a, 11a) to a pouring outlet (10b, 11b). The liquid passageways (10, 11) comprise upstand portions (10c, 11c) extending into the containers B, C and separate upper bend portions (10d, 11d) leading to the outlets (10b, 11b). The angle between the longitudinal axes of the outlets (10b, 11b) is approximately 120 DEG for concurrent pouring of the liquids to opposite sides of a glass F. Pouring in parallel streams, to different locations in a receptacle and sequential pouring are also described. Separate air passageways (30, 31) extend from air inlet parts (30a, 31a) to air outlets (30b, 31b). The air flow is controlled by an air pot (50) over each outlet (30b, 31b). The air pots (50) are sized and positioned so that fluid does not enter the air passageways on pouring and only air is forced up the air passageways on finishing pouring.

Description: POURER FOR POURING AT LEAST TWO DIFFERENT LIQUIDS Introduction The invention relates to a pourer and in particular to a pourer for pouring liquids such as alcoholic beverage liqueurs and the like from two or more containers. A new liqueur product has recently been introduced which is provided in a single container having two sub- containers, one for each liqueur. One of the liqueurs is white coloured cream liqueur and the other is a dark coloured coffee liqueur. It is intended that a user pours the dark liqueur from one of the sub-containers into a glass and the white liqueur is then poured down the sidewall of the glass to lie on top of the dark liqueur and present an aesthetically pleasing and pleasant tasting liqueur drink. Conventionally, the sub-containers are closed by separate stoppers which are removed as required for pouring a desired liqueur from its sub-container. This invention is particularly directed towards providing a pourer for pouring from two or more sub-containers of this type. Statements of Invention According to the invention there is provided a pourer for pouring at least two different liquids from containers, the pourer comprising a pourer body section associated with each container, each pourer body section having an air passageway and a pouring passageway, the passageways being arranged for substantially concurrent pouring of the different liquids from the containers. One of the advantages of the invention is in providing a pourer which allows two different liquids to be poured simultaneously. In a preferred body of the invention the pouring passageways are arranged for substantially concurrent pouring of the liquids into a receptacle such as a glass. In a particularly preferred embodiment of the invention, the passageways are arranged for substantially concurrent pouring of the liquids to different locations in a receptacle. The pouring of the separate liquids to different locations in a glass allows the liquids to be concurrently poured without substantial mixing. Thus, the liquids are allowed to separate to form a layered beverage. In a particularly preferred arrangement the passageways are arranged for substantially concurrent pouring of the liquids to opposite sides of a receptacle. Preferably, the angle between the axes of adjacent liquid outlets is at least 90°, most preferably approximately 120°. This is the preferred angle at which the liquids can be poured concurrently while avoiding substantial mixing. In a preferred embodiment of the invention the liquid passageway outlets are at substantially the same level. In a preferred embodiment of the invention, the air vent is offset from the associated liquid outlet. The offset between the fluid outlet and air vent facilitates free flow of liquid on pouring. In another embodiment of the invention the liquid passageway outlets are at different levels for pouring one liquid to a first location in a receptacle and another liquid to a second location in the receptacle at a different level to the first location in the receptacle. In this case preferably the liquid outlets are arranged for substantially concurrent pouring of one liquid to a side wall of the receptacle and another liquid to a base of the receptacle. Preferably the angle between th» axes of adjacent liquid outlets is approximately 90°. In another embodiment of the invention the passageways are arranged for substantially concurrent pouring of the liquids in substantially parallel streams. In this case the outlets from the liquid passageways may be in a substantially common place or may be offset in substantially parallel planes. In a particularly preferred aspect of this embodiment of the invention the passageways are arranged for substantially concurrent pouring of the liquids in substantially parallel streams to the same side of a receptacle. In a preferred arrangement, the air vent is located above the associated liquid outlet in the pouring position. This feature a s sists in preventing liquid entering the air passageway on pouring and facilitates replacement of the liquid dispensed from the container with air. In one embodiment of the invention, the air passageway includes a lower leg for extending into a container and an upper leg which is offset from the lower leg. Preferably, the upper leg extends substantially at right angles to the lower leg. This arrangement facilitates the desired advantageous positioning of the air vent offset from and above the liquid outlet. In a particularly preferred embodiment of the invention, the air passageway includes a constriction means to substantially prevent the flow of liquid through the air passageway. This constriction to prevent the flow of liquid through the air passageway may be provided, for example, at the transition between the lower and upper legs of the air passageway. In one embodiment of the invention, the lower leg includes an end portion, for example, in the form of a scarf portion to promote the flow of liquid from the inside of the air passageway back into a container when a container is up-righted after pouring. This feature also prevents a bubble film forming across the aperture/tube bore due to surface tension effects. In an especially preferred embodiment of the invention, an air flow management means is provided at the outlet of the air passageway to promote the formation of air bubbles during pouring and to substantially retain air at the outlet on finishing pouring to substantially prevent liquid passing through the air passageway on finishing pouring. Such an air flow management means has been found to be particularly advantageous in managing the flow of air and indeed the flow of liquid during operation of the pourer. In a preferred embodiment of the invention the air flow management means comprises an air pot over the outlet of the air passageway. Preferably the outlet of the air passageway defines, together with the air pot, an air management volume. Preferably the air pot includes a base wall and a side wall which extends upwardly from the base wall, the base and/or side wall defining together with the outlet of the air passageway, the air management volume. Ideally the air pot includes a location means for receiving the air passageway. Preferably the location means comprises an entry hole in a top wall of the air pot through which the air passageway extends. It has been found that in the particular case illustrated the air management volume should preferably be from 1 ml to 3 ml, and most preferably approximately 1.6 ml to help promote the formation of air bubbles. Preferably the air pot includes drain hole to allow liquid to drain from the pot. In a preferred arrangement the air pot is shaped to provide a lead-in for the pourer on placement on a container. In one embodiment of the invention, the main pourer body includes a receptacle locating means to locate the pourer in a desired pouring position. The receptacle locating means may, for example, comprise a receptacle rim engaging recess in the pourer body. This feature aids consumer compliance by facilitating correct positioning of the pourer relative to the receptacle. In another embodiment of the invention the pourer includes a valve means for closing the liquid and/or air passageways and actuating means for operating the valve means to open the passageways. In this case the actuating means may be adjacent to the receptacle locating means so that the valve means is operated to open the passageways only if the pourer and receptacle are in a defined pouring position. In an especially preferred embodiment of the invention the pouring passageways are arranged for concurrent pouring of the liquids at a predetermined volume ratio. In a preferred embodiment of the invention, the pourer passageways and/or outlets are of different cross- sectional areas for concurrent pouring at a predetermined volume ratio. This feature has the advantage of facilitating concurrent pouring of different liquids at desired volumes, for example, at a volume ratio of 2:1. In a preferred embodiment of the invention each pouring passageway includes an upstand portion which extends from the pourer body section into a container. Preferably each liquid passageway includes an upper bend portion extending from the upstand portion to an outlet portion. In a preferred embodiment of the invention the upstand portion is generally elliptical in cross section to provide a smooth transition between the upstand and bend portions. In one arrangement the angle, in front view, between the longitudinal axis of the bend portion of each passageway and the horizontal is from 40° to 80°, preferably approximately 60°. In a preferred arrangement the angle, in side view, between the longitudinal axis of the bend portion of each pouring passageway and the horizontal is from 20° to 60°, preferably approximately 40°. In a preferred embodiment of the invention the angle between the longitudinal axis of the outlet of each liquid passageway and the horizontal is from 2° to 12°, preferably approximately 8°. In one embodiment of the invention, for particularly good liquid flow on pouring and on uprighting the bore of each liquid pouring passageway gradually increases from the liquid outlet towards the liquid inlet. The bore ideally should gradually increase from the end of the nozzle to the end of the upstand. This ensures that, on completion of pouring, any fluid remaining in the bore is encouraged to fall back into thf mottle and not form a slug that could block the fluid p ch. In another embodiment of each invention each pouring passageway is inclined from a lower inlet to an upper pouring outlet. Preferably each pouring passageway is inclined at an angle of between 10° and 30°. Most preferably the pouring passageway is inclined at an angle of approximately 20°. In possibly the simplest construction of pourer according to the invention for ease of manufacture each liquid passageway is defined by a substantially straight tube. In this case the liquid outlet is defined in the simplest construction by an open end of the tube. Alternatively, in an arrangement which is slightly more difficult to manufacture the end of the tube is closed and the outlet is defined by an opening in the sidewall of the tube. In this case the openings in the sidewalls of the tubes are preferably oppositely directed. In this simplest construction preferably each air passageway is defined by a substantially straight tube. In one embodiment of the invention, for ease of manufacturing, the pourer body may include a separate cover for each pouring outlet. In a preferred embodiment of the invention, the pourer includes a sealing cap. This feature not only improves the shelf life of the liquids to be poured, but also reduces the risk of contamination, including cross contamination between the liquids . This feature opens up the possibility of providing a pourer with a cap which is fitted permanently to the containers. In this case of twin fluids with associated air passageways a single cap may be used to seal the passageways. Preferably, the cap includes a fluid seal for sealing each fluid outlet. This feature maintains the shelf-life of the liquid and also assists in preventing accidental spillage of the liquids, for example, if the containers are inverted. Preferably also, the cap includes an air seal for sealing each air vent. This similarly assists in maintaining the shelf life of liquids and also in preventing accidental spillage. In a particularly preferred embodiment of the invention, the cap is arranged to prevent removal of the cap on lifting. The advantage of this feature is in avoiding the cap being accidentally removed from the pourer if the container to which the pourer is fitted is lifted by the cap only. To achieve this, preferably the cap is at least partially of flexible material and is a push-on fit to the body of the pourer. Preferably, the sidewall means of the cap is pressed inwardly to release the cap from the pourer. This feature ensures that a user must intentionally decide to remove the cap before the cap becomes disengaged from the pourer body. Preferably, the cap is configured to roll-on to the pourer body on fitting. The roll-on feature allows for ease of fitting of the cap, while at the same time ensuring that the seals engage with the liquid outlets and air vents. Thus, preferably the fluid seal engages with the fluid outlet either on rolling on or off of the cap into position on the pourer. In a preferred embodiment of the invention, one or both of the pourer body and cap includes a ramp over which the cap rides on rolling into the closed position on the pourer. This feature ensures positive engagement of the cap in the closed position. Typically, the ramp is provided on the pourer body for ease of operation. In a preferred arrangement, the ramp defines a lead-in for engaging the air seal with the air vent on movement of the cap into the closed position. In one embodiment of the invention, the cap or pourer body includes a projection for engaging with a complementary recers on the other of the pourer body or cap when the cap is ved to the closed position. This ensures a positive engagement on closure of the cap so that the cap cannot be removed accidentally. In another aspect the invention provides a pourer for pouring at least two different liquids from containers, the pourer comprising a pourer body section associated with each container, each pourer body section having an air passageway and a pouring passageway, the pourer including a holding chamber into which a second liquid is delivered while a first liquid is being poured and release means for releasing the second stored liquid when the first liquid has been poured. This pourer allows for sequential pouring of different liquids. In this case the release means comprises a valve means and an actuator associated with the valve means. Preferably the actuator is mounted on the pourer. In a particularly preferred embodiment of the invention each pourer body section includes engagement means for engaging an associated container outlet. In another aspect of the invention provides a bottle having at least two separate containers for different liquids and having a pourer according to the various aspects of the invention described above. In one case the bottle and pourer are integral. However, generally it may be more convenient that each container has a neck and the pourer is fitted to the necks of the containers. In one embodiment of the invention the bottle includes a jig to align the necks of adjacent containers on assembly of the containers so that the surfaces of the container necks presented to the pourer are substantially in a common plane and spaced suitably. Preferably the jig includes recesses to receive the respective container necks, the jig having lugs which project into the recesses to contact the respective container necks. In a preferred arrangement there are three lugs associated with each recess to define a three point contact with a respective container neck. Preferably a first lug is located substantially on the centre line of the container neck and a second and third lug are located on the other side of the container neck, the second and third lugs being equi-angularly spaced from the centre line of the container neck. In one embodiment of the invention for ease of fitting each pourer body section includes snap projections to snap fittingly engage a corresponding formation on the container neck. In this case preferably seal is interposed between each pourer body section and the associated container. Preferably the seal is of a compressible elastomeric material. Any of the features of the pourers according to the invention described above may advantageously be applied to pouring a single fluid. In another aspect of the invention there is provided a pourer having a pouring passageway and an air vent passageway wherein an air flow management means is provided at the outlet of the air passageway to promote the formation of air bubbles during pouring and to substantially retain air at the outlet on finishing pouring to substantially prevent liquid passing through the air passageway on finishing pouring. Such an air flow management means has been found to be particularly advantageous in managing the flow of air and indeed the flow of liquid during operation of a pourer. In a preferred embodiment of the invention the air flow management means comprises an air pot over the outlet of the air passageway. Preferably the outlet of the air passageway defines, together with the air pot, an air management volume. Preferably the air pot includes a base wall and a side wall which extends upwardly from the base wall, the base and/or side wall defining together with the outlet of the air passageway, the air management volume. Ideally the air pot includes a location means for receiving the air passageway. Preferably the location means comprises an entry hole in a top wall of the air pot through which the air passageway extends. It has been found that for the particular case illustrated the air management volume should preferably be from 1 ml to 3 ml, and most preferably approximately 1.6 ml. Preferably the air pot includes a drain hole. In a preferred embodiment of the invention the air pot is shaped to provide a lead-in for the pourer on placement on a container. In a preferred embodiment of the invention the air passageway includes an end portion to promote the flow of liquid from the inside surface of the air passageway back into a container. Preferably the end portion of the air passageway is a scarf portion. In a further aspect provides a pourer comprising a pourer body section associated with each liquid, each pourer body section having a pouring passageway, the pouring passageways being arranged for pouring the liquids at a predetermined ratio. Preferably the pouring passageways and/or liquid outlets are of different cross section area for concurrent pouring at a predetermined volume ratio. In a preferred arrangement each pouring passageway includes an upstand portion which extends from the pourer body section into an associated container. Preferably each liquid passageway includes an upper bend portion extending from the upstand portion to an outlet portion. In a preferred arrangement the upstand portion is generally elliptical in cross section to provide a smooth transition between the upstand and bend portions. Preferably the pourer includes an air passageway associated with each liquid passageway. In a particularly preferred embodiment of this aspect of the invention an air flow management means is provided at the outlet of the air passageway to promote the formation of air bubbles during pouring and to substantially retain air at the outlet on finishing pouring to substantially prevent liquid passing through the air passageway on finishing pouring. Preferably the air flow management means comprises an air pot over the outlet of the air passageway. Preferably the outlet of the air passageway defines, together with the air pot, an air management volume. In one arrangement the air pot includes a base wall and a side wall which extends upwardly from the base wall, the base and/or side wall defining together with the outlet of the air passageway, the air management volume. Preferably the air pot includes a location means for receiving the air passageway. Ideally the location means comprises an entry hole in a top wall of the air pot through which the air passageway extends. In the particular case illustrated preferably the air management volume is from 1 ml to 3 ml, most preferably 1.6 ml. Preferably the air pot includes a drain hole. In one embodiment of the invention for ease of fitting preferably the air pot is shaped to provide a lead-in for the pourer in placement on a container. In a particular embodiment of the invention the air passageway includes an end portion to promote the flow of liquid from the inside surface of the air passageway back into a container. Typically the end portion of the air passageway is a scarf portion.

Detailed Description of Drawings Referring to the drawings and initially to Figs. 1 to 39, there is illustrated a pourer according to the invention and indicated generally by the reference numeral 1 for pouring from two or more containers. In this case, the pourer 1 is used for pouring dark and white liqueurs from a bottle A comprising two adjacent containers B,C having respective outlet necks D,E. The pourer 1 comprises a main pourer body 2 having a pourer body section 3, 4 associated with each container B,C. Each pourer body section 3, 4 has an engagement means which may be in the form of a depending skirt portion 6 for engaging with an associated container outlet 7 or may snap-fittingly engage the container necks as described in more detail below. Each pourer body section 3,4 has a pouring passageway 10,11 respectively which extends from a liquid inlet 10a,11a from an associated container B,C, to a pouring outlet 10b,lib. The liquid passageways 10,11 comprise upstand portions 10c,lie extending in use into a container B,C, and separate upper bend portions lOd, lid extending from the upstand portions 10c,llc to an outlet portion 10e,lle. The bend portions 10d,lld and outlet portions 10e,lle are formed as one unit and subsequently assembled to the main body section 2 of the pourer as will be particularly apparent from Figs. 6 to 11. The upstand portions 10c,lie are generally elliptical in cross section to provide a smooth transition between the upstand and the bend portions 10d,lld which are generally circular in cross section. Referring particularly to Figs. 11A to 11C the angle alpha (Fig- HA), between, in the front view, the longitudinal axis of the bend portion lid, lOd of each pouring passageway 10,11 and the horizontal defines how close together the nozzles are for pouring. The angle alpha is preferably from 40° to 80°, most preferably about 60°. This allows the liquids to be poured into a relatively small glass while achieving a good spread of the fluids, on pouring. The angle beta (Fig. 11) between, in the side view, the longitudinal axis of the bend portion lld,10d and the horizontal defines the overall height and projection of the outlet nozzles of the fluid passageways 10,11. This angle beta is preferably from 20 to 60°, most preferably about 40°. This encourages pouring in the correct direction and directing the fluids into a glass. The angle gamma (Fig. 11C) between the longitudinal axis at the outlet lib, 10b of each passageway 10,11 and the horizontal effectively inclines the outlet portion 10e,lle of the fluid passageways to encourage fluid to drain back down into the containers when pouring is complete. The angle gamma is preferably from 2° to 12°, most preferably, about 8°. In the case of black coloured liquid, the upstand portion 10c promotes suckback of liquid in the pouring passageway 10 into the bottle. In the case of white liquid which is more viscous than the black, the upstand portion lie retards the flow of white liquid so that the black liquid exits its pouring passageway slightly in advance of the white liquid. This assists separation in the receptacle as it allows the black layer to be formed first. The pourer passageways 10,11 are of different cross- sectional areas for concurrent pouring of the liquids at a predetermined volume ratio. For example, in the case of white and dark liqueurs, the passageways may be designed to pour a volume ratio of the liquids of 2:1. The length of the fluid passageways may also be adjusted to assist in tuning the volume ratio. The passageways 10, 11 are in this case arranged for substantially concurrent pouring of the liquids from the containers into a receptacle such as a glass F as illustrated in Fig. 5. In this case, the passageways 10, 11 are arranged for substantially concurrent pouring of the liquids to different locations in the glass F. The locations are in this preferred arrangement on opposite sides of the glass F. The angle between the longitudinal axes of the outlets 10b, lib is at least 90° and preferably, approximately 120° for substantially concurrent pouring of the liquids to the opposite sides of the glass F. This provides particularly good spread of the liquids when poured into a wide glass at a spacing that allows pouring into a smaller glass. The bore of the liquid passageways 10,11 gradually increases from the outlets towards the inlet. This ensures that, on completion of pouring, any fluid remaining in the bore is encouraged to fall back into the bottle and not form a slug that may block the fluid path. The liquid outlets are also sharp and shaped for drip control. The sealing surface area is reduced. The inside surfaces of the pouring passageways also have smooth profiles to facilitate pouring and prevent slugs of liquid forming on uprighting of bottle. The main pourer body 2 has separate air passageways 30, 31 associated with each liquid passageway 10, 11, respectively. The air passageways 30, 31 extend from respective air inlet ports 30a, 31a to respective air outlets 30b, 31b. The inlets 30a, 31a are located above the associated fluid outlets 10b, lib in the pouring position and are offset from the fluid outlets. It will be noted that the air passageways 30,31 extend further in use into the associated containers B,C so that when the bottle is fully tipped, air will continue to come out of the air passageway because of the lower static head in this passageway. A lower leg 35, 36 extends into a liquid container and an upper leg 37, 38 extends substantially at right angles to the lower leg 35, 36, respectively, so that the air is turned in the air passageways 30, 31 through substantially 90°. The arrangement will be particularly apparent from Figs. 6 and 11. Each air passageway 30,31 includes a constriction 40 to substantially prevent the flow of fluid through the air passageway while allowing air to flow through the passageway as required, and also preventing the formation of a slug of fluid in the air way. It will be noted that the air outlets 30b, 31b are defined by scarf portions at the lower end of the legs 35, 36 to facilitate drain-back of any liquid caught in the inner surface of the passageways 30, 31 back into the respective containers . An air flow management means is provided at the outlet 30b,31b of each air passageway 30,31 to promote the formulation of air bubbles during pouring and to substantially retain air at the outlet 30b,31b on finishing pouring to substantially prevent liquid passing through the air passageways 30,31 when pouring is finished. In this case the air flow management means comprises an air pot 50 over each outlet 30b,31b of the air passageways 30,31. The outlet 30b,31b of the air passageways 30,31 define, together with the respective air pots 50, an air management volume. In the particular case illustrated we have found that this air management volume is preferably from 1 ml to 3 ml, most preferably approximately 1.6 ml. The volume of air held in the pot 50 means that when a bottle is put upright from a pouring position, and the liquid drains back down the fluid passageway, only air is forced up the air passageway to maintain equilibrium. The air pot 50 is of a size to allow air and not fluid to be forced up the air tube on finishing pouring. This allows suck-back of fluid down the fluid pipe. The air pot is also of a size to produce large enough air bubbles for even flow of fluid through the fluid pipes. In this case, the air pot 50 includes a base wall 51, a side wall 52 and a top wall 53. The base 50 and side wall 52 together with the outlet 30b,31b of the air passageway 30,31 define the air management volume. A location means for receiving the air passageway 30,31 is in this case defined by an entry hole 54 in the top wall 53 through which the air passageway 30,31 extends. The air pot 50 is in this case of plastics material and is ultrasonically welded to the air passageway 30,31 and the upstand portion 10c,lie of the adjacent fluid passageway. It will be noted that the base wall 51 of the air pot 50 is shaped to provide a lead-in for the pourer on placement on a bottle. Referring particularly to Fig. 6, it will be noted that the pot 50 extends in use for a distance above the upper edge of the scarf 31b. It will be appreciated that the disposition of the air pots 50 relative to the scarfs 31b can be reversed from that illustrated in the drawings. The exit diameter of the pots 50 is important to facilitate the formation of bubbles. If this diameter is too small, surface tension effects may prevent bubble formation. Each air pot 50 may have a drain hole 55 (Fig. 6) in the base wall 51. The drain hole 55 may be typically about 0.5 mm diameter to allow liquid to drain from the pot 50 when the bottle is upright while avoiding bubbling air when liquid is being poured. The pourer body illustrated in Figs. 7 to 11 is covered by two separate cover parts 57, 58 which are shown in detail in Figs. 12 to 18. The cover parts 57, 58 include reinforcing ribs 59. Inwardly extending projections 60 are provided on one of the cover parts 58 for engagement on assembly in corresponding recesses 61 in lugs 62 carried by the other cover part 57. The cover parts are shown assembled particularly in Fig. 14. Other features of the cover parts 57, 58 are determined by the necessary locations for the fluid outlets and air vents. It will be noted that the cover parts 57,58 define, on assembly, a shape including a recess 63 which assists in indicating to a user the direction of pouring. The cover parts 57, 58 are retained in an assembled configuration by a label top L which interlocks with the cover parts 57, 58 as will be particularly apparent from Figs. 16 and 20. The table top L is a planar curve to facilitate labelling, for example with pouring instructions. Referring to Figs. 19 to 32, a closure cap 64 for the pourer is illustrated in detail. The cap 64 comprises a closure body part 65 and a sealing cap part 66 which is engaged on assembly with the body part 65 as illustrated particularly in Fig. 20. The cap 64 is arranged to prevent removal of the cap on lifting of the cap. For this reason, the cap is at least partially of flexible material and is a push-on fit to the body of the pourer. In this case, the sidewall means of the cap is pressed inwardly at the locations indicated by the arrows 61 and thumbgrip features 62 (see Figs. 1 and 3) to release the cap from the pourer. The cap 64 is configured to roll-on to the pourer body on fitting as will be explained in more detail below. The cap 64 includes separate fluid seals 68, 69 for sealing each of the fluid outlets 10b, lib, on assembly of the cap to the pourer body. Similarly, the cap includes an air vent seal 70 for sealing each of the air vents 30a, 31a on assembly of the cap to the pourer body. The cover parts 57, 58 of the pourer body are provided with recesses 90, 91 just above the associated air vents 30a, 31a. The sealing part 66 of the cap 64 is provided with inwardly extending projections 92, 93 which engage in the corresponding recesses 90, 91 on rolling on of the cap to the pourer body as illustrated particularly in Figs. 26 to 31. It will be noted that the pourer body includes a ramp part 95 over which the projections 92, 93 on the cap 64 ride on rolling of the cap into the closed position. The ramp 95 defines a lead-in for engaging the projections 92, 93 with the associated recesses 90, 91 and consequently for engaging the air seal 70 with the air vents 30a, 31a. The cap 64 is ramped in the vertical plane to ease the cap over inner er'ges of the pourer. It is also poured in the horizontal plane to assist in centralising the cap, on fitting. During rolling-on of the cap 64, it will be apparent that the fluid outlet seals 68, 69 are not rubbed against the pourer body but rather are arranged to engage the fluid outlets 10b, lib in substantially face-to-face relationship on closure of the cap. The cap also includes a further projection 97 on another face thereof, for engaging with the face of the pourer body opposite from the air vents 30a, 31a. This assists in locating and fixing the cap 64 in position. To release the cap 64, the sides of the cap 64 are squeezed as indicated by the arrows and thumbgrips. This at least partially releases the projections 92, 93 and 97 from the associated recesses and allows the cap 64 to be rolled-off as illustrated. For re-sealing, the cap 64 is rolled back on to the pourer body and pushed downwardly to the sealing position. In the sealing position, even if the bottle A to which the pourer 1 is fitted is lifted by lifting the cap 64, the cap 64 and pourer 1 will remain in position avoiding accidental breakages and spillages. The seals 68,69,70 are typically of EVOPRENE™ material having a shore hardness of 50°. It will be appreciated that the main pourer body may include a receptacle locating means to locate the pourer in a desired pouring position. The receptacle locating means may, for example, comprise a receptacle rim engaging recess in the pourer to guide the user for correct orientation of the pourer for concurrent pouring of liquids into a receptacle. A recess 74 in the cover parts 57, 58 assists in performing this function, an assembly and in use. Referring to Figs. 33 to 36, there is illustrated a jig 100 which may be used in association with the pourer as illustrated in Figs. 38 and 39. The jig 100 is to align the necks 101, 102 of adjacent bottles 103, 104, on assembly so that the surfaces of the bottle necks 101,102 presented to the pourer are in a common plane, allowing the pourer to be fitted correctly to each bottle 103, 104 and giving substantially constant centre distances between bottles of various size tolerances. The jig 100 is a single flat piece of plastics material having recesses to receive the respective bottle necks 101, 102. There is a three point contact with a circular recess in each neck 101, 102 by lugs 105 which project into the recesses to contact the bottle necks 101, 102, on assembly. In use, the jig is fitted around the necks 101, 102 of the bottles 103, 104 on adhesive bonding of the bottles and ensures that the bottle necks 101, 102 are maintained in alignment. A first lug 105a is located substantially on the center line of the container neck and second and third lugs 105b,105C are located on the other side of the container neck. The second and third lugs 105b, 105c are equi- angularly spaced from the center line of the container neck. Referring to Figs. 37A and 37B, there is illustrated another jig 115 which is similar to the jig of Figs. 33 to 36 and like parts are assigned the same reference numerals. The design is intended to strengthen the jig 115 thereby preventing the sub-containers being squeezed too tightly during bending. It will be noted that the jig 115 in this case includes flat portions lib which define stop surfaces to ensure that even if bottles 101,102 are squeezed tightly together, on assembly, there is a minimum spacing X between the bottles 101,102. In this way a pourer may be correctly inserted and the correct sealing obtained. The main body of the pourer snap-fittingly engages the necks 101, 102 of the bottles 103, 104. Each pourer body section 3, 4 has six equispaced snap projections 120 which ride over enlarged flanges of the bottle necks 101, 102, on fitting of the pourer to the bottles 103, 104. A seal 125 is interposed between each bottle neck 101, 102 and the respective pourer body section. Each seal 125 is of a compressible elastomeric material so that the pourer may be easily push fitted onto the bottle necks 101, 102 without the requirement of a large pushing force. The seal is typically of EVOPRENE * material having a shore hardness of 27. Referring to Fig. 40 there is illustrated another pourer 190 which is similar to the pourer described above and has some similar features. This is a very simple construction of pourer which may be readily moulded in plastics material using simple open and stud moulding tools. In this case there are two liquid passageways which are defined by substantially straight tubes 191,192. In this case the tubes 191,192 are open at both ends for ease of moulding. Air passageways are provided by substantially straight tubes 193,194 respectively fitted with air flow management pots 195,196 respectively. The air pots 195,196 are similar to those described above and have similar features. The tubes 191,192,193,194 are mounted in a support body 197 which is assembled to a main body 198 and covered by a cap 199. The pourer 190 will provide concurrent pouring in parallel streams of liquid. It will be noted that there is only one internal sealing interface - that between the pourer 190 and a bottle to which it is fitted. Depending on the nature of the fluids to be poured in some cases air pots may not be essential. All four outlets may be at the same level for ease of sealing. The cap 199 is also of simple construction and a simple seal may be positioned inside the cap 199 or provided as a separate sealing flap 199A as illustrated. In addition, the air and fluid passageways may be formed adjacent to one another, for example in a single passageway with a physical longitudinally extending divider. The air and liquid passageways, may, for example, be concentric. Referring to Fig. 41 there is illustrated another pourer 200 which is similar to the pourer 190 of Fig. 40 and like parts are assigned the same reference numerals. In this case the outlet end of each liquid tube 191,192 is closed and the liquid outlet is defined by an opening 201 in the sidewall of the liquid tube 191,192. The openings 201 are oppositely directed to deliver two streams of liquid to opposite sides of a receptacle. Referring to Figs. 42 and 43, there is illustrated a pourer according to the invention and indicated generally by the reference 210 for pouring from two or one containers. In this case the pourer 210 is used for pouring dark and white liqueurs from sub-containers A, B, the sub-containers A, B having respective outlets C, D. The pourer 210 comprises a pourer body 212 having pourer body sections 213,214 which may be moulded simultaneously or may be separately formed and subsequently assembled. Each pourer body section 213,214 has engaging means, in this case in the form of a bung 215 for engaging a respective container outlet C, D. Pouring passageways 216,217 extend through the respective pourer body sections 213,214, the passageways 216,217 being arranged for pouring the liqueurs from the containers A, B in a predetermined desired manner. In this case the passageways 216,217 are arranged for concurrent pouring from each of the containers A, B in substantially parallel streams. The passageways 216,217 are arranged to avoid mixing of the materials from the containers A, B before entry into a receptacle such as a glass into which liqueurs are to be poured and before a predetermined location in the receptacle. Typically the pourer passageways 216,217 are of different cross-sectional area over at least portion of their length for concurrent pouring at predetermined volume ratio. In this case each pourer passageway 216,217 is inclined with respect to a central longitudinal axis of the respective pourer body section 213,214 from a lower inlet 215 as close as possible to the base of the sub-container to an upper pouring outlet 216. Typically the angle of inclination is between 10° and 30°' and most preferably approximately 20°. It will also be noted that each passageway 216,217 includes a bend portion 227 adjacent the outlet 226 for controlled pouring and drip prevention. The upper bend portion 227 extends at an angle to the longitudinal axis of the container which is less than 90° to prevent drip. The pourer body section 213 is also contoured at 228 to substantially prevent drip. Air vent means are provided for each pourer body section. In the case of the embodiment illustrated in Figs. 42 and 43 the air vent means is provided by an air vent passageway 230 extending through the pourer body section 213 from an inlet 231 opening into the container A to an upper outlet 232. In the alternative arrangement illustrated in Fig. 44 the air vent means in provided by an air vent passageway 235 defined between the pourer body section 213 and the container outlet C to which the body section 215 is fitted. The pourer body 212 also includes a receptacle locating means, in this case in the form of a receptacle rim engaging recess 240 which engages the rim of a glass to facilitate concurrent pouring of the liqueur beverages on the same side of a glass. In use, the pourer 210 is fitted to the outlets C, D of the containers A, B. In a closed position a snap-over cap 245 is engaged with the pourer 210 as will be apparent from Fig. 43. When it is desired to pour from the containers A, B into a glass, the cap 245 is removed and the recess 240 of the pourer body is carefully engaged with the rim of the glass. The bottle with the pourer 210 attached is carefully tilted to a pouring position the flow of the different beverage liqueurs being poured from the containers A, B being controlled by the arrangement of the pouring passageways 216,217. Mixing of the beverages is avoided before they reach the surfaces of the glass. This is achieved in this case by pouring through the passaαeways 216,217 in substantially parallel streams on the same side of the glass. When a desired quantity has being poured the bottle is tilted back to the upright position and the cap 245 is replaced. Referring to Fig. 45, there is illustrated a pourer 250 which is similar in concept to the pourer described with reference to Figs. 42 and 43 and like parts are assigned the same reference numerals. In this case the outlets from the pouring passageways 216 are extended and air vent passageway tubes 251 extend further into the body of the containers A, B. This pourer is particularly suitable for use with a roll-on type cap as described above with reference to the pourers of Figs. 1 to 39. Referring to Figs. 46 to 48 there is illustrated another pourer 300 ace -ding to the invention. Each liquid tube is formed from two sections 301,302. A lower section 302 passes through the plane of a top of a bottle 303 at an angle β to the bottle neck centreline, and protrudes into the neck a distance h. The lower tube section 302 is cut off parallel to the neck wall 304, such that a gap y is provided between the end of the tube section " O2 and the wall 304 in use. The lower tube section 302 ay alternatively be formed as a drilling in a solid component, emerging through the side and end faces of the components as shown. In this instance the distance y refers to the distance between the neck wall and the opposite side of the drilling bore. The lower tube section 302 terminates at a point on the neck bore at 90° from a line joining the neck centres of the two bottles 306,307 on the 'pouring' side of the bottles . The upper tube section 302 is set at an angle 0 to the horizontal (with the bottle neck centreline vertical) and is cut off at an angle 0 to the vertical. The angle 01 is such that the top of the tube is longer than the bottom (ie 01>0°) . The end of the upper tube section 302 is at a distance x from a vertical line taken up from the neck inner wall 304. The distances x and y are arranged such that x>y. This ensures that as the bottle 306/307 is returned to the vertical position after pouring, the upper and lower sections 301,302 of the liquid tube form a syphon, drawing the liquid remaining in the tube back into the bottle, and preventing dripping from the liquid outlet. The upper and lower tube sections 301,302 have diameters dl and d2 respectively. A restriction 310 is formed in the upper tube section 302, having an effective diameter d3. This restriction 310 is adjusted to give the required flow rate of liquid. The size of the restriction is different for 'black' and 'white' sides of the pourer. The restriction 310 adds to the natural restriction of the liquid tube, and therefore depends on the liquid tube length and the diameters dl and d2. The restriction 160 may be a simple orifice, but is preferably a partial tube blockage formed to restrict the upper part of the upper tube, leaving a clear drain path for liquid back into the bottle. The restriction 310 is ideally placed close to the joint between upper and lower tube sections 301,302 of the liquid tube, and may form part of the joint. The expansion from d3 to dl should be smooth. An air vent tube 311 may be a single straight tube of diameter d4 as shown, or have curves to accommodate external shape restrictions. In use, the air vent tube 311 must lie above the liquid tube 301,302 to ensure liquid does not enter the air vent tube 311. This may be achieved by keeping the air vent tube centreline to the left (as drawn) of the liquid tube centreline at all points. The top of the air vent tube 311 should ideally be level with or above the top of the liquid tube 301,302. It may however be possible to terminate the air tube lower. The bottom of the air vent tube 311 must protrude below the lowest part of the liquid tube 302 by a distance hi. From the view of Fig. 48, the lower end of the air vent tube 311 should be diametrically opposite the liquid tube, and as close to the bottle neck wall as practicable (ie dimension z as small as possible) . The bottom of the air vent tube 311 is formed at an angle 02 to its centreline, with the angle oriented such that the lowest part of the tube 311 is away from the wall of the bottle neck 304. The bottom of the air tube is fitted with an air retention pot 315, of diameter d5 and depth j. The function of the pot 315 is to trap a bubble of air around the air tube 311, preventing liquid entry and eliminating 'spurting' from the liquid tube when the bottle is returned to upright after pour ng. The relatively large diameter of the pot 315 also ensures large air bubbles form during pouring, giving a smoother pour without 'glugging'. - 36 - The centre-to-centre distance of the bottle necks (c) may vary with individual bottles . The pourer incorporates features which allow for this variation. The distance between the two liquid tube outlets (e) is set to allow easy pouring into the majority of glass sizes . The distance between the two air inlets has not been found to be critical. Referring particularly to Figs. 47 and 48 typical dimensions are : β 10°-20° 0 6° 01 0°-30° 02 30° x (y+2mm) y 2 - 3mm z 1 - 2mm c 35mm nominal e 15mm dl 5 - 6mm d2 5mm d3 3.0mm (white liquid) 3.5mm (black liquid) d4 5mm d5 13mm j 12mm (Air pot volume : 1.6ml approx) h 0 - 15 mm hi 20mm Referring tc Fig. 49 there is illustrated a modified pourer 350 similar to the pourer described above with reference to Figs. 45 to 48. The pourer 350 incorporates an actuator 351 activated by the rim of a glass. The air tubes are sealed until the actuator 351 is pushed against a glass. As the actuator 351 operates, it causes the air holes to be uncovered allowing air into the bottle and thus allowing fluid out of the liquid delivery tubes. This forces the user to place the bottle in the correct orientation relative to the glass, so that the fluid flows down the side of the glass. Referring to Fig. 50 there is illustrated another pourer 360 according to the invention which is also arranged for concurrent pouring of the beverage liqueurs. In this case the pourer 360 has pouring passageways 361, 362 which are arranged for pouring the beverage liqueurs to different locations in a receptacle. In this case, the passageway 361 is an elongate passageway for the dark coloured beverage liqueur and is arranged for delivering the dark coloured liqueur to the base of a receptacle and the second passageway 362 is arranged for delivering white liqueur to a side wall of the receptacle so that it is delivered above the dark liqueur. Referring to Fig. 51 to 53 there is illustrated a further pourer 370 according to the invention. The pourer 370 is in this case, arranged to facilitate consecutive pouring of the beverage liqueurs. Separate outlets 375 are provided for each liqueur. The pourer 370 includes a holding chamber 371 into which the white coloured beverage liqueur 372 is delivered while the dark coloured liqueur 373 is being poured. When a desired quantity of the dark liqueur 373 has been poured or the white chamber is filled a handle 377 is engaged to release a valve member 374 allowing the flow of white liqueur 372 from the holding chamber 371 while preventing pouring of the dark liqueur 373. The handle 377 is pivotably mounted to the pourer body at 378 and engages a pivotally mounted lever 379. The lever 379 operates a rod 380 to which the valve member 374 is attached. A coil spring 381 biasses the valve member 374 into a position closing an outlet 385 from the chamber 371 as illustrated in Fig. 52. On operation of the handle 377 the lever 379 depresses the rod 380 against the biassing of the spring 381 to move the valve member 374 to open the outlet 385 and allowing white liqueur from the chamber 371 to flow to the outlet 375. The pourer 370 includes air passageways 390 and fluid passageways 391. In the closed position (Fig. 53) of the handle 377 a seal 395 closes the air passageway 390 associated with the dark liquid 373. Many variations on the specific embodiments of the invention will be readily apparent. It will be readily appreciated in particular that various air flow and fluid flow management features of the pourer of Figs. 1 to 39 may be applied to the other pourers described. This also applies to the cap and jig features. Indeed, many of these features may be applied to pourers for single fluids and are not necessarily therefore restricted in their application to twin fluids. The containers from which liquids are to be poured may be arranged one within the other, for example concentrically. While the invention has been described particularly for use in association with a two compartment bottle it is not limited to such an application. Any suitable container(s) may be employed. In particular the invention may be applied to three or more fluids, some of which may require to be maintained substantially separated. These and many other variations and modifications of the invention will be readily apparent and accordingly the invention is not limited to these embodiments in their various aspects which may be varied in both construction and detail.
